One of the steeper, more feral trails at Waterdog, this is a quick way to get to the bottom. It's the original trail in this area, now largely serviced by Ohlone Trail. While it's an old trail, it's also not on the official park map. Thus, you really only ever see bikes on this one. One fun feature is a skinny wooden ramp through a tree, meeting up with the trail below the following switchback. It's climbable, but hard in that direction, particularly near the tree mentioned above.
